Understanding air quality in our region

Air quality is a public health issue. It directly affects our daily lives, our health and our quality of life. The diagnosis of the Territorial Climate Air Energy Plan identifies the main sources of atmospheric pollution in the Cœur de France area and guides our action.

In 2022, several air pollutants were analysed, including fine particles (PM10 and PM2.5), nitrogen oxides (NOx), ammonia (NH₃), sulphur dioxide (SO₂) and non-methane volatile organic compounds (NMVOCs).

The agricultural sector is the main source of atmospheric pollutant emissions in the region. In particular, it is responsible for almost all ammonia emissions, mainly linked to the spreading of nitrogen fertilisers and livestock effluents. Ammonia contributes to the formation of fine particles in the atmosphere.

The residential sector is the second largest source of emissions. Fine particles, certain volatile organic compounds and sulphur dioxide come partly from wood-burning when it is done with old or inefficient equipment, but also from the use of fossil fuels.

Road transport is also a major contributor, particularly for nitrogen oxides. These emissions are mainly linked to diesel vehicles. Traffic on the main routes, including the A71 motorway, adds to this impact.

Overall, emissions of atmospheric pollutants have fallen since 2008, reflecting technological and regulatory improvements. However, certain sectors continue to play a key role in local pollution, and further efforts are needed to achieve lasting improvements in air quality.

Compared with the region as a whole, the situation in the region is close to the averages observed. This means that the issues encountered locally are representative of those in the region's rural areas.

Impact on health and the living environment

Air pollution has a direct impact on health, particularly on the respiratory and cardiovascular systems. Fine particles penetrate deep into the lungs and can aggravate certain pathologies. Hot spells, which are set to become more frequent with climate change, also encourage the formation of ozone and can cause a temporary deterioration in air quality.

Air quality is therefore closely linked to climate, energy and agricultural issues. Action taken to reduce greenhouse gas emissions often also helps to improve the air we breathe.

Our commitment to improving air quality

Our action aims to act on the main sources identified.

In the residential sector, this means renovating homes and replacing old heating equipment with more efficient, lower-emission systems.

In terms of mobility, we are working to develop alternatives to the private car, encouraging car-sharing and promoting soft mobility wherever possible.

In the agricultural sector, support for practices that limit ammonia emissions is an important lever, in conjunction with local stakeholders.

Improving air quality means protecting the health of residents, particularly the most vulnerable, while contributing to the transition to a more energy-efficient and climate-friendly economy. The Climate Plan sets the framework for this collective action, in the service of a healthier environment for all.
